The purpose of this study is to develop a nature friendly education program that would support ecological literacy of preschool children and to examine the effects of the program on their ecological knowledge and positive attitudes toward nature. The subjects of the study were 59 children from two child-care centers located at Gyeonggi Province. 30 preschoolers from one center were allocated into an experimental group, while 29 preschoolers from the other center were regarded as the control group. The program was composed of 24 sessions, performed three times a week for 20-30 minutes from May to June 2009. The instrument included the knowledge and attitudes toward the environmental scale for preschool children. The following results were obtained. First, the experimental group was found to attain higher level of ecological knowledge and more positive attitudes about nature as a result of the program. Second, after the program was administrated, the experimental group showed higher level of the knowledge and more positive attitudes about nature than the control group. These results suggest a program which conducts within a integrated teaching frame of meeting and getting familiar with nature and taking care of animals and plants, can become an effective early childhood education tool which fosters positive attitudes and knowledge concerning the environment.

This study has been conducted on the nonequivalent control group pretest-posttest design in quasi experimental basis and newly born premature infants from intensive care unit of G Medical University Hospital in Inchon Metropolitan were selected in two groups of 21 infants each. The first group for experimental and the other for control. Data has been collected form October 30, 1997 to August 29, 1998. For the experimental group tactile and kinesthetic stimulation was applied 2 times a day for 10 days(10 : 00~11 : 00 hours in the morning and 17 : 00~18 : 00 in the afternoon). As a weight weighing instrument. electronic indicator scale(Cas Co. korea) was used. To determine urine cortisol concentration level in stress hormone, radio immune assay method was used. And high performance liquid chlomatography was used to determine urine norepinephrine, concentration level To determine behavior status, tools developed by Anderson et at(1990) and remodeled by Kim Hee-Sook(1996) were used. Collected data were analyzed with the SAS program using x$^2$-test, student t-test, repeated measures ANOVA and paired t -test. The result were as follow. 1. As for the daily weight gain. the experimental group showed first change in weight and this group also showed higher weight in the average weight than the control group. Statistically, however, there was no significant factor between the two group. 2. The cortisol concentration in urine showed decrease in the experimental group norepinephrine concentration in urine showed increase in both experimental and control groups. No statistical significance was shown between the two groups. 3. In the aspect of behavior status. the experimental group showed statistical significance by showing inactive in the state of alert and conversion to a positive state than the control group. In conclusion, the sensory stimulation in this study showed a positive aspect through there was no statistical significance in the weight gain and urine stress hormone concentration. In the behavior status, there was statistical significance in the frequency of staying inactive in the state of alert and conversion to a positive state.

This study was performed to survey the achievements in problem solving by the inquiring experiment, which was done by the superior group in the traditional cocepts-centered written tests. The purpose of this study was to identify characteristics of inquiring experimental assessment by analyzing differences between concepts-centered written and inquiring experimental tests. The subjects of this study was 211 applicants. They are the superior group of the 9th grade students, and score in the top 1% of total achievements percentage in school. They also have passed the primary entrance examination. The inquiring experimental test was developed according to the curriculum in school, and is composed of 5 subcategories: problem-perception and formulating hypothesis, designing an experiment, carring out an experiment, recording data and drawing conculsion, and generalizing conculsions and communicaton. The checklists of each subcategory were made and testing methods were divided into observation and report. The major results of this study are as follows: 1. The achievements in each subcategory of inquiring experimental performance were very low in the superior group who took the concepts-centered written tests. 2. The results of factor and correlation analyses in this study confirmed the abilities measured by inquiring experimental assessment differed from abilities measured by existing tests. These results indicated that even students who achieved high in scientific knowledge, these abilities were not automatically transformed inquiry process which many other abilities were integrated into. Therefore, problem solving ability requires integrated abilities which are fostered by inquiring experimental tasks. This suggests that new instrument for assessment must be developed to measure integrating ability especially where scientifically gifted students are selected, or where entrance examinations to the science schools are administered.

Purpose: The purpose of this study were to develop a respiratory communicable disease prevention program for preschoolers and measure it's effects. Method: The respiratory communicable disease prevention program for preschoolers consisted of texts, cartoons, photographs, discussions, demonstrations, puzzle games, die games, compensation/reinforcement, and token economy which were directed under the systematic design of instruction by Dick ％amp; Carey. This study was a quasi experimental study under the nonequivalent control group with pretest-posttest design. The subjects of this study were 45 preschool children who are attending 3 different district nursery schools and they were matched by the age, pretest knowledge, and pretest behavior. The instrument used in this study was criterion referenced test items that were developed by a researcher for evaluating the subject's knowledge, attitude, and behavior about respiratory communicable disease prevention. A pretest was administered a week before treatment. Experimental group Ⅰ was administered by the treatment of respiratory communicable disease prevention program. Experimental group Ⅱ was administered by above program with token economy program. The posttest was conducted on the eighth day. The third test for behavior was completed 15th day. To determine the effect of the program, the data were analyzed by the SAS 6.12 program with Kruskal Wallis test, ANCOVA, ANOVA, Duncan's test and paired t-test. Result: 1) There was a significant difference in knowledge between the experimental groups and control group(F=5.89, P=0.0197). 2) There was a significant difference in attitude between the experimental groups and control group(F=3.29, P=0.0469). 3) There was a non-significant difference in behavior between the experimental groups and control group(F=0.00, P=0.9512). 4) In the experimental groupⅡ, there was highly significant increase in behavior after token economy(t=4.5252, P=0.0005). Conclusion: It was found that the respiratory communicable disease prevention program for preschool children was effective in changing the preschoolers' knowledge and attitude on the respiratory communicable disease prevention, but not enough for changing the preschoolers' behavior. Token economy was improved as an effective and strong method for inducing desirable changes of preschoolers' behavior.

This is a quasi-experimental research to test the effect of using a nursing care scale. This study identified the effects of using a nursing care scale influencing on the nursing performance and job satisfaction. The subjects consisted of 63 staff nurses in 8 medical and surgical units of one hospital affiliated to university hospital in Seoul, and assigned to experimental and control group conveniently. The data were collected in September and December, 1992. The evaluation of the nursing performance were measured by the instrument from a nursing care scale of one univerrsity hospital and job satisfaction was measured by Stamp's Scale (1978). The data were analyzed by percentage distribution, 2-test, Mann-Whitney U Wilcoxon Rank Sum W test, ANCOVA and T-test. The summarized results were as follows : 1. The nursing performance of the experimental group showed markedly increase about 13 areas of nursing care. However no significant difference in the nursing performance between the two groups was found. 2. There was a significant difference in the nursing performance between the experimental and the control group about 7 areas of nursing records(W=22.0, P<.05). 3. After using a nursing scale, there was a significant difference in the nursing performance about nursing care and nursing records between the experimental and the control group(W=25.0, P<.05). Comparing before using a nursing scale with after, there was no significant difference in the nursing performance between two groups. 4. There was no significant difference in job satisfaction between the experimental and the control group. The main reasons for there being no defference in two groups could be the small size sample and the procedure of intervention. Further comparative study is needed using more strictly controlled procedure of intervention.

The purpose of this study was to determine the effect of nursing education in diabetes patient, and to define the strategy to promote their sick-roll behavior, self efficacy. The quasi-experimental design was designed non-equivalent control group, non-synchronized design. The study had been done by investigating the experimental group and control group through the questionnaire on 58 patients who had been hospitalized and visiting out-patient department in K hospital in Pusan from June 1, 1998 to September 30, 1998. Individual diabetes education was carried out experimental group for the average 45 minutes. Self-efficacy was measured by Diabetes Management Self-efficacy Instrument developed by Park(1984). Data was collected before and after the experimentation. Collected data was analyzed by means of frequency, percentage, chi-square test, mean, standard deviation, and t-test with SPSS/PC program. The results were summarized as follows : 1. 'The experimental group which received the individual diabetes education should be higher in self-efficacy than control group' was not supported. 2. 'The experimental group which received the individual diabetes education should be higher in sick-roll behavior than control group' was not supported(P=.043). In conclusion, the patient who received individual diabetes education showed the increase in degree of sick - roll behavior of diabetes patients. So individual diabetes education had been judged the nursing intervention to improve sick-roll behavior of diabetes patients. But there was no effect about self-efficacy so to have the program which can improve self-efficacy is needed.
